How much does the Niigata HN1250-S cost?
Price estimate
We do not have a price for the Niigata HN1250-S that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
A rectangular pallet is what distinguishes the Niigata HN1250-S. At 1,250 mm × 1,000 mm (49.2 in × 39.4 in) it is longer than it is deep, which suits bed-like and frame-like parts that overhang a square table. This horizontal machining center pairs that pallet with travels of 2,200 mm (86.6 in) in X, 1,800 mm (70.9 in) in Y and 1,200 mm (47.2 in) in Z, for a workpiece of φ2,500 mm × 2,000 mm.
Compared with the HN1000-S, the gain is in X and Y only. Z is unchanged, and the pallet load is slightly lower: 3,200 kg (7,055 lb) as standard and 4,700 kg (10,362 lb) as an option. Buyers should read that as a machine for larger, not heavier, work.
It shares the HN-S series mechanics. Roller guides carry the X and Z axes and a hand-scraped sliding way carries Y, and rapid traverse is 41 m/min on all three. The standard spindle is the two-stage geared unit: BT50, 6,000 min-1, 1,200 N·m (885 lb-ft) and 37 kW (49.6 hp).
Two optional spindles change the character of the machine. The high torque specification raises torque to 1,948 N·m with 30 kW, still at 6,000 min-1, and is the choice for difficult-to-cut materials. The high-power specification runs to 15,000 min-1 with 45 kW and 400 N·m. Tool capacity is 62 as standard, with chain magazines up to 255 tools and matrix magazines up to 230 tools as options. The table indexes in 1° steps unless the 0.001° option is taken.

Strengths & Limitations
Strengths
- 1,250 mm × 1,000 mm rectangular pallet for long workpieces
- Workpiece up to φ2,500 mm × 2,000 mm with 1,800 mm of Y travel
- 41 m/min rapid traverse on X, Y and Z
- Standard 37 kW (49.6 hp), 1,200 N·m (885 lb-ft) geared spindle

Frequently Asked Questions
01
A rectangular pallet of 1,250 mm × 1,000 mm. It carries 3,200 kg (7,055 lb) as standard and 4,700 kg (10,362 lb) as an option. The maximum workpiece is φ2,500 mm in swing by 2,000 mm in height.
02
The HN1250-S has more X and Y travel, 2,200 mm and 1,800 mm against 2,030 mm and 1,650 mm on the HN1000-S, and a larger workpiece envelope. Z travel, rapids and spindle choices are the same. The HN1000-S carries a little more weight, 3,500 kg as standard.
03
Rapid traverse is 41 m/min (1,614 ipm) on X, Y and Z. X travel (table left/right) is 2,200 mm, Y (spindle up and down) is 1,800 mm and Z (column front/back) is 1,200 mm.
04
Yes. The standard spindle gives 1,200 N·m and 37 kW. The optional high torque specification gives 1,948 N·m (1,437 lb-ft) with 30 kW at the same 6,000 min-1 limit. A 15,000 min-1 high-power spindle with 45 kW is the other option.
